Effect of timing of first clinical mastitis occurrence on lactational and reproductive performance of Holstein dairy cows.
Objectives of this study were to determine the influence of timing of first clinical mastitis case occurrence on lactational and reproductive performance in high producing lactating dairy cows duringExpand

Effects of dietary supplemental fish oil during the peripartum period on blood metabolites and hepatic fatty acid compositions and total triacylglycerol concentrations of multiparous Holstein cows.
The objectives were to evaluate the effects of dietary fish oil on plasma metabolite, hepatic fatty acid composition, and total triacylglycerol concentrations. Multiparous Holstein cows (n = 42) wereExpand

Rumen-protected methionine compared with rumen-protected choline improves immunometabolic status in dairy cows during the peripartal period.
The immunometabolic status of peripartal cows is altered due to changes in liver function, inflammation, and oxidative stress. Nutritional management during this physiological state can affect theExpand

Temperament influences endotoxin-induced changes in rectal temperature, sickness behavior, and plasma epinephrine concentrations in bulls
This study was designed to determine the influence of temperament on endotoxin-induced changes in body temperature, sickness behavior, and stress hormone concentrations in cattle. Brahman bulls wereExpand

Administration of anesthetic and analgesic prevent the suppression of many leukocyte responses following surgical castration and physical dehorning.
The objectives of the current research were to determine the physiological effects and responses of many leukocytes following surgical castration and/(or) physical dehorning and the influence ofExpand

Plane of nutrition influences the performance, innate leukocyte responses, and resistance to an oral Salmonella enterica serotype Typhimurium challenge in Jersey calves.
Two experiments investigated how plane of nutrition influences performance, leukocyte responses, and resistance to an oral Salmonella enterica serotype Typhimurium challenge. In experiment 1, 46 (2±1Expand

The effects of early weaning on innate immune responses of Holstein calves.
The objectives of this study were to compare innate immune responses of calves weaned early (EW; n=23; weaned at 23.7 ± 2.3 d of age) with those of conventionally weaned calves (CW; n=22; weaned atExpand

Modifying the acute phase response of Jersey calves by supplementing milk replacer with omega-3 fatty acids from fish oil.
Fifty-one Jersey bull calves (5 +/- 1 d old) were assigned to 1 of 3 milk replacers to determine the effects of increasing doses of n-3 fatty acids from fish oil on the acute phase response after anExpand
